The present invention relates to covers for containers, and is more directly concerned with a liquid dispensing cover for a container for storing liquid.
Use of liquid dispensing covers for liquid containers holding liquids are well known in the art. Such covers often form part of, or are connected or connectable to, containers, for example glasses or cups, for storing liquid for drinking and provide a dispenser through which liquid may pass to be dispensed, for example released or poured, typically into the mouth of a user for drinking of the liquid.
Such dispensers often include spouts, dispensing apertures, or the like through which the liquid may pass. The remainder of the cover sealingly mates or co-operates with the container to sealingly impede spillage or escape of the liquid therefrom. For example, such covers may often be connected to a rim or top end of the container which defines a container aperture for the container. In such cases, the cover sealingly engages the container top end and covers the container aperture to impede escape or release of the liquid therethrough. Thus, dispensing of the liquid is limited to passage through the dispenser, typically situated proximal an edge or side of the cover for convenient placement of the mouth or lips of the user thereupon for drinking the liquid. Unfortunately, such covers often allow spillage of the liquid through the dispenser, especially if the dispenser means has no closing means, such as an aperture cover, flap, or like for closing the dispenser is provided. Further, even when such closing means is present, it must often, inconveniently, be engaged and disengaged by the user's hand. Such is the case, for example, for conventional covers which have flaps extending over the dispensing aperture as the closing means, the flap being foldable back and forth between open and closed configurations to selectively uncover and recover the dispensing aperture. Obviously, such constraints can render closure and opening of the cover aperture by the user quite cumbersome, and even dangerous, when the liquid is a hot liquid and/or when user is engaged in other activities requiring use of the user's hands, for example driving.
Accordingly, there is a need for an improved liquid dispensing cover.
It is therefore a general object of the present invention to provide an improved liquid dispensing cover.
An advantage of the present invention is that the liquid dispensing cover impedes spillage of the liquid stored in the container.
Another advantage of the present invention is that the liquid stored in the container may be easily dispensed through the cover with a minimum risk of spillage.
A further advantage of the present invention is that the cover may be selectively opened to dispense the liquid and subsequently closed without use of the user's hands.
Still another advantage of the present invention is that the cover includes a dispensing recess for temporarily containing inadvertently spilled liquid and redirecting that liquid into the container.
Yet another advantage of the present invention is that the cover is made out of a single piece of material, preferably by plastic molding.
According to one aspect of the present invention, there is provided a liquid dispensing cover for a container for a liquid, the container having a container side wall with a generally circular open container top end, the container top end having an outwardly protruding container flange extending circumferentially therearound, the cover comprising:
In another aspect, there is provided a liquid dispensing cover for a container for a liquid, the container having a closed container bottom end and an open container top end with a container side extending therebetween, the cover comprising:

The recess bottom wall 40 is sealingly, yet resiliently, connected to the recess side wall 36 around the distal portion 42 and has a free edge 50, detached from the recess side wall 36, extending along the proximal portion 44. When the dispensing recess 32 is in a default closed configuration, shown generally as 52, the free edge 50 is resiliently biased against the side wall 36 and intersects therewith around the proximal portion 44. Thus, dispensing flow or spillage of the liquid L between the walls 36, 40 and out of the dispensing recess 32 is impeded. However, when an inwardly directed force, as shown by arrow A in
Advantageously, as the free edge 50 extends along the proximal portion 44, when the dispensing recess 32 is in the open configuration 54, liquid L flowing out of the dispensing recess 32 must do so through the proximal portion 44. Thus, the liquid L is dispensed through the proximal portion 44 in proximity to the cover side wall 20, typically in proximity to a user's lips which facilitates drinking of the liquid L and reduces risk of spillage. To further facilitate pouring or flow of the liquid L through the proximal portion 44 when the dispensing recess 32 is in the open configuration 54, the recess side walls 36 and recess bottom wall 40 preferably taper inwardly from the distal portion 42 to the proximal portion 44. Conveniently, as the protrusion top 48 of the protrusion 46 is substantially level with the top surface 38 or extends slightly vertically therebeyond, and is situated proximal the cover side wall 20, a user can easily exert the inwardly directed force with his or her upper lip by placing the upper lip against the protrusion top 48 and tilting the container 16 and cover 10 towards his or her lips. Thus, the user may easily place the cover in the open configuration 54 when placing the cover 10 against his or lips and tipping the container 16 and cover 12 upwardly to drink from the container 16. Accordingly, the cover 10, and notably the dispensing recess 32, can be placed in the open configuration 54 by using a conventional drinking motion. Similarly, when the container 16 and cover 12 are tilted away from the upper lip, the upper lip is separated from the protrusion top 48. Thus, the inwardly directed force is released and the dispensing recess 32 is biased back into the closed configuration 52. Accordingly, the dispensing recess 32 may be moved between the closed and open configurations 52, 54 without manipulation of the dispensing recess 32 by the user's hands.
Preferably, but not compulsorily, the side recess walls 36 extend inwardly until they are substantially vertically aligned with or slightly above, along with the recess bottom wall 40, the bottom side end 22 or the top end 12 of the container 16. Thus, the container 16 may be fully filled with Liquid L without the Liquid L overflowing through the dispensing recess 32. Optionally, if desired, the free edge 50 may initially be breakably, and preferably sealingly, connected to the recess side wall 36, for example with a weak bonding agent or the like. Alternatively, the cover 10 could be fabricated such that the free edge 50 and cover side wall 36 are initially molded together at a thin, breakable intersection between edge 50 and wall 36, preferably a thinner or weakened breakable portion 70 of the recess side wall 36 which extends adjacently proximal the edge 50. By exerting the inwardly (downwardly) directed force on the free edge 50, however, the sealing connection between the free edge 50 and the recess side wall 36 can be broken along the breakable portion 70, thus allowing the dispensing recess 32 to be moved between the closed and open configurations 52, 54 as previously described. Until the sealing connection between the free edge 50 and cover side wall 36 is broken, however, the dispensing recess 32 would be completely sealed, preventing accidental spillage therefrom.
Advantageously, the round, cylindrical form of the recess protrusion 46, as well as its location extending on the recess bottom wall 40 through both the proximal and distal portions 44, 42, prevents the wall 40 at the proximal portion 44 from becoming permanently bent inwardly by repeated exertion of the inwardly directed force, thus maintaining the resiliency of the recessed portion 32, and notably the recess bottom wall 40 at the proximal portion 44, between the closed and open configurations 52, 54. To ensure that such resiliency is maintained, the movable edge 50 and breakable portion 70 must extend around recess side wall 36 and recess bottom wall 40 to opposing edge ends 92 that are aligned with, i.e. extend alongside, opposite faces or quadrants 102 of proximal cylindrical half 83 of the recess protrusion 46. More specifically, the proximal cylindrical half 83 is represented by the end of edge 50 at line 81, extending between lines 82 and 84, within region 83, situated proximal the distal portion 42 and cover side wall 20. The distal cylindrical half 87 is situated within the distal portion 42.
Advantageously a small air aperture 90 or slit, disposed in the top wall 26 proximal the cover side wall 20 but generally opposite the dispensing recess 32, allows for flow of air in and out of the container 16 through cover 10. The small size of the air aperture 90 or slit, as well as positioning thereof proximal the cover side wall 20 but generally opposite the dispensing recess 32, allows for the flow of air as the container 16 is tilted back and for the during use while impeding inadvertent flow of liquid through the aperture 90.

Cover 10″ has an openable and closeable dispensing recess, shown generally as 224, recessing, i.e. depending, inwardly and downwardly from the cover top wall 216 and through which Liquid L may be dispensed from the container 16 through the cover 10″. For cover 10″, the dispensing recess 224 is defined by proximal recess side wall 212 and distal recess side wall 114, and resiliently openable and closable recess bottom wall 228. The proximal recess side wall 212 recesses radially inwardly, i.e. towards the bottom side end 220 of cover 10″, from the inner groove wall 202 of adjacent portion of groove 218 extending between first and second recess end walls 110. The first and second recess end walls 110 also recess radially inwardly, from the cover top wall 216′, and taper inwardly from the proximal recess side wall 212 to the distal recess side wall 114. As the proximal recess side wall 212 extends contiguously adjacent groove 218, it is curved and arcuate in shape. At the same time, distal recess side wall 114, distal the groove 218 and also extending radially inwardly relative the cover top wall 216, is also curved around a curbed, generally semi-circular arc, from the first recess end wall 110 to the second recess end wall 110, and is spaced inwardly from the proximal recess side wall 212. Thus, the dispensing recess 224 is generally curved and arcuate in shape and extends generally adjacent the inner groove wall 202 of groove 218. The distal recess side wall 114, along with the cover top wall 216 adjacent thereto and extending between the end walls 110 define a generally semicircular button or recess protrusion 230 extending into the dispensing recess 224 and upwardly from recess bottom wall 228.
The recess bottom wall 228 extends from, and between, the bottom of the recess end walls 110, the distal recess side wall 114, and the proximal recess side wall 212 to provide the openable and closeable bottom 228 of the dispensing recess 224. Thus, the recess bottom wall 228 is connected to cover top wall 216 by walls 114, 110, 212 and is inwardly inset thereby relative to the cover top wall 216. As best shown in

The entrance opening 180 is of lesser thickness or width than the flange 208. The groove 218 is sized and shaped such that while the flange 208 is disposed in groove 218, for example when cover 10″ is connected to container 16, the flange 208 and groove 218, in particular the indented portion 164, cause the inner groove wall 202 and proximal recess side wall 212 contiguously adjacent thereto to bias inwardly. The inward biasing of the proximal recess side wall 212 when the cover 10″ is connected, along with the upward slanting of wall portions 124, 126, causes the proximal wall portion 124 to be biased upwardly and over the distal wall portion 126, with the distal wall portion 126 extending thereunder and in abutment therewith. Thus, when the cover 10″ is connected to the container 16, the indented portion 164, groove 218, and flange 208, along with container side wall 14 cooperate to bias inner wall portion 234 inwardly and upwardly to move the cover 10″ from the initial configuration 162 to the closed configuration 236. The cover 10″ may then be moved between configurations 236, 238 as previously described. When the cover 10″ is removed from the container 16, the proximal wall portion 124 is no longer biased upwardly and inwardly, and the cover 10″ returns to the initial configuration 162.
The cover top wall 216 and distal recess side wall 114 slope upwardly, beyond the vertical level of the top groove wall 206 of groove 218, between the recess end walls 110, in particular between the intersections with distal recess side wall 114 and recess end walls 110. Thus, the recess protrusion 230 slopes upwardly away from the rest of the cover top wall 216 with at least a portion of the protrusion 230, preferably adjacent the distal recess side wall 114 and end walls 110, extending vertically beyond the top groove wall 206. Therefore, the user can easily exert the inwardly directed force A, to place the cover 10″ in the open configuration 238, with his or her upper lip by placing the upper lip against the protrusion 230 and tilting the container 16 and cover 10″ upwardly in a conventional drinking motion. Similarly, when the container 16 and cover 10″ are tilted away from the upper lip, the upper lip is separated from the protrusion 230. The inwardly directed force A is therefore released and the recess bottom wall 228 is biased back into the closed configuration 236. Accordingly, the cover 10″ may be moved between the closed and open configurations 236, 238 without manipulation of the dispensing recess 224 by the user's hands. Advantageously, as the dispensing recess 224 and protrusion 230 are proximal the groove 218 and perimeter of cover 10″, when the cover 10″ is in open configuration 238, the liquid L is dispensed through the dispensing recess 224 in proximity to a user's lips.
An optional, but preferable, depression 154 in the cover top wall 216, extends circumferentially around the perimeter thereof adjacent inner groove wall 202, and the groove 218, with the exception of the dispensing recess 224. The depression 154 provides a trough 154 into which liquid L on the cover top 216 may drain into the dispensing recess 224. Optionally, the cover top wall 216 may slope upwardly commencing from distal top end 160 thereof, generally opposite recess 224, towards dispensing recess 224, with the cover top wall 216 at distal top end 160 situated vertically below the inner groove wall 202. Thus, liquid L on the cover top wall 216 may drain towards the distal top end 160 and into trough 154 and then from trough 154 to the dispensing recess 224. Alternatively, the cover top wall 216 may be shaped to curve downwardly from groove 218, depression 154, and protrusion 230 towards the center of cover top wall 216.
Optionally, if desired, the distal wall portion 126 may initially be breakably, and preferably sealingly, to the proximal wall portion 124 along edge 232, for example with a weak bonding agent or the like. Alternatively, the cover 10″ could be fabricated such that the proximal and distal wall portions 124, 126 are initially molded together at a thinner or otherwise weakened breakable intersection defining edge 232. However, by exerting the inwardly directed force A on bottom wall 228, and notably the distal wall portion 126, for example with the protrusion 230, the sealing connection between the wall portions 124, 126 can be broken along the edge 232. Alternatively, the sealing connection could be broken by inward and upward biasing of inner wall portion 124 when the cover 10″ is connected to container 16, as described previously.
The resilient biasing of the distal wall portion 126 from the closed configuration 236 to the open configuration 238 is provided by the round, preferably semi-circular shape of the distal recess side wall 114 and recess protrusion 230, along with the recess end walls 110, which slant downwardly and outwardly from the cover top wall 216 towards proximal recess side wall 212. In particular, to ensure that distal wall portion 126 does not become permanently bent inwardly by repeated exertion of the inwardly directed force A, the movable edge 232 must extend around distal wall portion 126 to opposing faces or quadrants of distal recess side wall 114.
The container 16 may be any type of conventional liquid container 16, such as a glass or cup, provided it provides a round opening at top end 12 and, for cover 10″, flange 208. Further, the container 16, while preferably made of paper or styrofoam, may be constructed of any material, including plastics, glass, or the like, typically used for such containers 16. The cover 10, 10′, 10″, while preferably, made of plastic or polyurethane, may be made of other materials conventionally used for covers for liquid containers 16.
